Add arch timer node to enable arch-timer support. MT6580 firmware doesn't correctly setup arch-timer frequency and CNTVOFF, add properties to workaround this. This set cpu enable-method to enable SMP. Signed-off-by: Scott Shu <scott.shu@mediatek.com> --- arch/arm/boot/dts/mt6580.dtsi | 20 ++++++++++++++++++++ 1 file changed, 20 insertions(+)
